Result The results showed that tissue culture seedlings cultured with disinfection seeds and fresh fruit seeds had higher survival rates, which could reached above 75.0%. Taken Pingguoli and Xiangshuili for cions, Shanli without root for rootstock, the survival rate of graft seedlings had obvious difference. And Xiangshuili for cions had higher survival rates. Taken Xiangshuili for cions, Shanli and Xiangshuili for rootstock, the survival rate of graft seedlings with root had higher survival rates than that without root. Added hormone to the media could improve the survival rate of micro-grafting plants, in the medium of MS+BA 1.0 mg/L+IBA 0.3 mg/L, the survival rate reached 86.7%.

结果］种子消毒处理及鲜果取种组培苗的成活率均较高，达75.0%以上；以香水梨和苹果梨为接穗，无根山梨为砧木时的嫁接苗成活率有显著差异，其中以香水梨为接穗的成活率较高；以香水梨为接穗，山梨和香水梨为砧木时，带根的材料嫁接时的成活率都显著高于无根嫁接苗的成活率；此外，添加植物生长调节物质可以有效提高嫁接成活率，在培养基MS+BA 1.0 mg/L+IBA 0.3 mg/L中嫁接苗的成活率最高，达86.7%。

Compact obturation is an important factor for root canal therapy, focusing on reducing the channel of entering root system through mouth and peripheral apical tissue and blocking excitant which is not completely removed during debriding and repairing root canal.

致密的封填是根管治疗成功的关键之一，其主要目的是为减少经由口腔或根尖周围组织渗透进入根管系统的信道，以及将根管清创、修形过程中无法完全移除的刺激物封闭于根管系统内。

Segments produced clusters of somatic embryos from embryogenic calli or directly from root apical meristems , and that also can convert into bud directly in the different tissue culture conditions. Modified media B5 with 1.0 mg.L-1 2,4 - D and 3.0mg.L~1 6-BA is suit to induce calli, and 0.5 mg.L-1 NAA is fit for somatic embryos inducement from calli. 6-BA encreased direct somatic embryogenesis on root tip distinctly,but NAA is retard it. NAA also prolong the time of root-tip convert into bud directly.

在改良B_5(微量元素为原来的1／3)中加入1.0mg.L~(-1)2，4—D和3.0mg.L~(-1)6-BA对离体根尖的愈伤组织诱导较为合适，0.5mg.L~(-1)NAA有利于从愈伤组织上产生体细胞胚；6-BA明显促进离体根尖直接产生类原球茎，而NAA则有阻碍作用；同时NAA的存在也使离体根尖直接成芽的时间延长。

With the Sand culture method, influences of different magnesium levels (0%、50%、100%、150%、200% and 300%) was explored to the wheat seedlings of different stages. Many targets such as plant height, root length, biomass, content of chlorophyll, activity of root, RGY, RGR and ratio of root to crown of the wheat were mensurated at the time of 7d, 15d and 30d of two leaves stage of wheat seedlings after their endosperms were removed at different magnesium levels.The results showed that different magnesium levels had unlike influences over the wheat seedlings.

以小麦为试材，采用砂基培养的方法，在镁浓度分别为对照组的0%、50%、100%、150%、200%和300%的营养基质上，培养剔除胚乳后的二叶期小麦幼苗7d、15d及30d，并分别测定该3个时间段小麦幼苗的株高、根长、地上部和地下部的生物量、叶绿素含量、根系活力以及相对生长速度、相对生长速率和根冠比等指标，研究不同供镁水平对不同时期小麦幼苗生长速率的影响。

Thank careless root to give me this chance, we also can try hard do, root wishing grass does better more, I can go for a long time careless root support!

谢谢草根给我这次机会，我们也会努力的做下去，祝草根越办越好，我会长期去草根支持！

And Changbai larch(Larix olgensis A.Henry)atdoubled CO2 concentration at seedling stage in growth-chamber and WI,HI of several dorminanttree species in MBKPF(1)Under 700μl·1-1 concentration of CO2,the stem height, stem diameter,main root length,root/shoot ratio and the relative proportions of biomass in root,stem and leaf of the seedlings ofKorean pine and Changbai larch had no significant change.

在700μL·L-1CO2条件下与正常浓度下相比较，在一个生长季后，红松、落叶松幼苗的苗高、地径、主根长、根茎比及生物量在根、茎、叶各器官中比例，差异不显著，对落叶松的侧枝数有影响；在第一、二次试验中，落叶松幼苗的平均每株生物量比在正常CO2浓度下大12.2％、14.2％，而红松幼苗的生物量分别减少3.9％、12.8％；红松、落叶松针叶叶绿素含量以及叶绿素a的相对含量在高浓度CO2下受到影响。

Methods The qualitative analyses of Kudzuvine root,Large-flowered skullcap root and Chinese goldthread of "Ge Gen Qin Lian" pocket preparation were finished.The reseachers analysed them with TLC method. Then they determined puerarin content of Kudzuvine root by TLC scan.

The main work of our research was to study the effects of the combination of enhanced UV-B radiation 0.35w·m~(-2 and Cadmium 1umol·L~(-1 on the growth, photosynthesis, elements absorption and relocation in mung bean seedlings at the initial stage of growth, and the involving mechanisms about the change of photosynthesis under the different treatments were studied also. It was shown that the heights root length, lateral root length, lateral root number, area of leaves, dry/fresh weight of the overground parts and underground part were all inhibited by the single factor and combinative factors.

本文以0.35w·m~(-2)剂量的UV-B模拟增强UV-B辐射和1μmol·L~(-1)Cd~(2+)模拟Cd~(2+)污染，研究了增强UV-B辐射和Cd~(2+)及其复合处理对绿豆幼苗生长、光合作用以及元素吸收和分配的影响，并对不同处理条件下绿豆幼苗光合作用的变化机制进行了比较深入的分析，获得结果如下：增强UV-B辐射和Cd~(2+)及其复合处理8天，绿豆幼苗植株高度、根长、侧根长、侧根数、叶面积、地上部分干/鲜重和根系干/鲜重均下降。
